Abstract: A system and a corresponding method for producing a UHT milk product by direct UHT heating. The method comprises feeding milk into a heating device, heating the milk by the heating device to increase a temperature of the milk to a first temperature within a range of 135 to 137° C., maintaining the milk inside the heating device at the first temperature for a first time within a range of 30 to 120 sec, feeding the heated milk into a homogenizing device, and homogenizing the heated milk by the homogenizing device, thereby producing the UHT milk product.

Abstract: The present invention relates to a method (200) for producing a heat-treated concentrated dairy product (cdp). The method (200) comprising the steps of passing (210) the dairy product (dp) under a pre-determined pressure through a reverse osmosis, RO, filter (110) at a first temperature, the pre-determined pressure being sufficient to allow reverse osmosis, thereby concentrating the dairy product (dp). Preheating (230) the concentrated dairy product (dp) at a second temperature for a second period of time to stabilize the concentrated dairy product (dp). Homogenizing (240) the stabilized concentrated dairy product (dp) to reduce a size of particles in the stabilized concentrated dairy product (dp). Heating (250) the stabilized concentrated dairy product (dp) at a third temperature for a third period of time to reduce microorganisms in the stabilized concentrated dairy product (dp), thereby forming the heat-treated concentrated dairy product (cdp).

Abstract: A method and system for forming a beverage mixture comprising protein is disclosed. The method comprises heating the beverage in a heat exchanger, transferring the beverage to a hold loop located outside of the heat exchanger, and denaturizing the protein within the hold loop for a residence time, after the beverage is heated in the heat exchanger such that the denaturizing occurs outside of the heat exchanger to prevent fouling of the heat exchanger. The system comprises a beverage forming tank, a heat exchanger for heating the beverage, and a first hold loop separate from the heat exchanger, which is configured to hold the beverage for a residence time to denaturize a protein in the beverage.

Abstract: A method of sterilizing a liquid milk based product comprises indirect preheating of the product and final heating to a sterilization temperature 140.degree.-150.degree. C. by direct steam injection. The product is cooled by so called flash-cooling at which steam corresponding to the added amount of steam is evaporated. The product is cooled by indirect cooling. It is now proposed that the product prior to the flash-cooling is cooled from the sterilization temperature 140.degree.-150.degree. C. to a temperature in the interval 90.degree.-120.degree. C. in an indirect, first cooling step after which the product is cooled by flash-cooling to a temperature of 70.degree.-85.degree. C. The apparatus for sterilization comprises a balance vessel (1) connected to an indirectly working first heat exchanger (4) for heating of the milk based product. A steam injection nozzle (6) is arranged in a pipe line out from the heat exchanger (4).
